Dundee United are weighing up an appeal against a Uefa fine for a fan invading the pitch during July's Europa League qualifier against Slask Wroclaw.

United chairman Stephen Thompson called the 5,000 euro penalty "ridiculous".

"We will wait until Uefa furnish us with their reasons for the decision before deciding whether to appeal or not," he added.

"It's ridiculous, especially when you consider everything else that went on surrounding the game."

United beat Slask Wroclaw 3-2 at Tannadice, only to tumble out of the tournament on the away goals rule.

Some 2,000 visiting fans helped generate a fantastic atmosphere inside the stadium but there were arrests following violent clashes in Dundee after the match.

"It is quite incredible that some Polish fans cause trouble throughout the city centre, with extra police drafted in from other parts of the country to deal with them - yet nothing has happened about that," added Thompson.

"Last year we had to spend £50,000 bringing Tannadice up to standard for the game against AEK Athens. It seems that there are double standards operating against British clubs in Europe.

"I am disgusted by the whole thing. Our club does not have a blemish on our record of playing 40 years in Europe.

"The fan walked onto the park picked up up a bit of paper or something and walked straight back off again."
